Suction

Suction is the process or action of drawing fluid or gas by reducing the pressure difference between two areas. In the medical field, suction is used in various procedures and treatments, such as respiratory therapy, surgery, and wound care.

Medical Uses

Respiratory Therapy

In respiratory therapy, suction is used to remove mucus and other secretions from the airways. This is often necessary in patients who have difficulty clearing their own airways, such as those with chronic obstructive pulmonary disease (COPD) or cystic fibrosis, or those who are intubated or on mechanical ventilation.

Surgery

During surgery, suction is used to remove blood and other fluids from the surgical site to maintain a clear view for the surgeon. This is typically done with a suction device or aspirator.

Wound Care

In wound care, suction is used in negative pressure wound therapy (NPWT). This involves applying a vacuum to a wound to promote healing by drawing out fluid and promoting blood flow to the area.

Types of Suction Devices

There are several types of suction devices used in healthcare, including:

• Manual suction devices: These are hand-operated devices used to clear the airway. They are often used in emergency situations or when electrical power is not available.
• Wall-mounted suction devices: These are typically found in hospital rooms and operating theaters. They are connected to the building's central suction system.
• Portable suction devices: These are battery-operated devices that can be used in various settings, including home care and transport.

Risks and Complications

While suction is generally safe, it can sometimes cause complications, such as:

• Infection: This can occur if the suction device is not properly cleaned and sterilized.
• Tissue damage: This can occur if the suction is too strong or if it is applied for too long.
• Hypoxia: This can occur if too much oxygen is removed from the airway during suction.
